Cursed Technique: Polymirrorism

Avery weaponizes reflections, cracks, and liquefied mirrors.

All reflective surfaces within 60 ft are under their control.

If no reflective surface exists, Avery may create spectral mirror panels (AC 15, 20 HP each).

Reflection Authority

As a bonus action, Avery may:

• Swap places with a reflection within 60 ft.

• Cause a creature to take damage by striking its reflection instead.

When a creature within 60 ft takes damage, Avery can use their reaction to reduce the damage by half and reflect the other half as force damage to another creature within 30 ft.

Actions

Multiattack

Avery makes two Shard Lash attacks.

Shard Lash

Ranged Spell Attack: +10 to hit, range 120 ft., one target.
Hit: 19 (3d8 + 5) force damage.

If the target is adjacent to a reflective surface, the attack can originate from the surface instead of Avery.

Mercury Phase (Recharge 5–6)

Reflective surfaces in a 30-ft radius liquefy for 1 minute.

Area becomes difficult terrain for enemies.

Creatures starting their turn in the area must succeed on a DC 18 Dexterity saving throw or:

• Be restrained until end of turn

• Take 14 (4d6) force damage

Avery may move through this area without penalty.

Shattered Alignment (1/Day)

Avery creates 3 fractured duplicates.

Each duplicate:

• AC 16

• 30 HP

• Deals half damage

Duplicates act on Avery’s initiative.

If destroyed, they explode in glass shards, forcing creatures within 10 ft to make a DC 18 Dex save or take 10 (3d6) force damage.

Faultline Waltz (Recharge 4–6)

Avery tears a crack in space in a 40-ft line.

Creatures in the line must make a DC 18 Dexterity saving throw.

On a failure:

• Take 36 (8d8) force damage

• Be knocked prone

On success:

• Half damage

• Remain standing

The line becomes unstable terrain; the next attack passing through it redirects at a 90-degree angle.

Reaction

Reverse Surface

When a creature within 60 ft makes an attack, Avery forces it to make a DC 18 Charisma saving throw.

On failure:

• The creature attacks its own reflection instead.

• The attack automatically misses.

• The creature takes 14 (4d6) psychic damage.

Legendary Actions (3 per round)

Mirror Step. Teleport up to 30 ft between reflections.

Shard Pulse. Deal 10 (3d6) force damage to a creature touching a reflective surface.

Crack Reality (Costs 2 Actions). Create a floating mirror panel granting Avery half cover.

Domain Equivalent — Infinite Atrium: Prism of Becoming (1/Day)

For 1 minute:

• The battlefield becomes fully reflective.

• Avery can teleport freely between any two points in the area.

• All attacks against Avery have disadvantage.

• When Avery hits with Shard Lash, it creates a second delayed hit at the start of the target’s next turn (automatic 2d8 force damage).

Creatures starting their turn must succeed on a DC 18 Wisdom saving throw or become disoriented (speed halved, disadvantage on Perception checks).
